Hi there! I'm Hainiu, a second-year PhD student at King's College London, affiliated with KCL NLP. I'm fortunate to be supervised by Professor Yulan He (primary, Department of Informatics), Professor Caroline Catmur (secondary, Department of Psychology), and Dr. Jinhua Du (secondary, Huawei London Research Center). My research interest is Character-Centric Narrative Understanding, Theory-of-Mind in particular. My study is supported by an EPSRC-iCASE project jointly funded by UKRI, Huawei London Research Centre, and King's College London.

Before KCL, I was a Master's student at the University of Pennsylvania, where I was supervised by Professor Chris Callison-Burch. During my time at Penn, I worked closely with Li "Harry" Zhang, who is currently an assistant professor at Drexel University. Prior to that, I completed my undergraduate degree in Statistical Data Science at University of California, Davis, where I worked on Functional Principal Component Analysis and Curve Registration with Professor Jane-Ling Wang.

Previously, I worked as a Research Intern at Huawei London Research Centre, and as an AI Enginner Intern at Schlumberger BGC.

Apart from my work and research, I take pleasure in studying the scores of renowned programmatic symphonies, particularly Symphonie Fantastique by Hector Berlioz and Scheherazade by Rimsky-Korsakov. I had the fortune to play many iconic music pieces as a member of the UC Davis Concert Band and the UC Davis Symphony Orchestra.

My MBTI is ENTJ.
